Abstract

Compares the growth of defoliated and nondefoliated perennial plants, with an emphasis on the link between plant structure, growth, and response to defoliation.

Overview

This lesson will compare the growth of defoliated and nondefoliated perennial plants. The link between plant structure, growth, and response to defoliation is the emphasis of the lesson.

Objectives

  • Define the terms source, sink, photosynthesis, carbohydrate, apical meristem, lateral meristem, and residual leaf area.
  • Compare the differences in morphology (plant structure) and physiology (plant function) between a nondefoliated and defoliated plant.
  • Predict how a plant will respond to defoliation based on morphology, physiology, and the environment.
